Creation of a jigsaw puzzle using HTML5 Canvas and KineticJS – step 1

Before we start, let me tell you I hate jigsaw games on the web, but I have a little daughter who loves them and I wanted to try KineticJS, an HTML5 Canvas JavaScript framework which claims to enable high performance animations, transitions, node nesting, layering, filtering, caching, event handling for desktop and mobile applications, and much more.

So I messed a bit with the engine, until I got:

* A full screen canvas element (which KineticJS calls Stage)
* An external image loaded (featuring Princess Merida)
* Such image being splitted into rectangular pieces (currently I am working on “real jigsaw” shapes)
* Every piece ca be dragged and dropped around the canvas
* Picked up pieces are in front of the rest of the puzzle

This is the code, still unexplained as I am still experimenting with it
